While using an online tool to adjust the page size of your PDF might seem fast and easy, it has its glaring drawbacks.

  • Firstly, a PDF file size increase online tool will put a limit on how much you can increase. Online tools hardly work with heavy PDF files.
  • If more features are needed to resize or adjust your PDF files, they might not be there, and if available, an online tool usually charges you for it.
  • In case you want to edit the text of your PDF as you carry out an online PDF size increase, very few online tools have the features or capability to allow you to do more. For instance, an offline tool such as PDFelement allows you to edit your PDF too as you resize your PDF file.
  • It's also quite hard to come up with or increase the size of PDF files enriched with such media as surveys, images, videos, and other rich media. Desktop software is much better in such a scenario considering its huge number of features and capabilities. Most online tools cannot help you much beyond simple functions.
  • Also, online tools are only used largely by individuals and not small, medium-level, or large companies. As you might already have guessed, the privacy and security of confidential documents is a huge concern today, and most companies aren't willing to see their private files hosted or accessed online, even within their browsers and business premises.

Essentially, increasing PDF size online might be simple, but if you want other functionalities to edit and transform your PDFs, you might want to try a superb, feature-rich PDF desktop tool such as PDFelement.
